Boston Acoustics GT-RSL

This GT-RSL remote subwoofer level control from Boston Acoustics eliminates the problem of varying bass levels in your music selections. The dash-mount knob connects to your Boston Acoustics GT Series amplifiers with its 13-foot cable so you can adjust the sound from the front seat of your car. Not a bass boost, this controller adjusts the level of your sub amplifier so you'll get consistent bass tones no matter what the volume. Warranty: 1 year.
